采用可靠性评估的方法，对船体总纵强度的安全水平可作出合理的评价。
Using reliability assessment method, we can obtain proper assessment of hull longitudinal strength safety level.
研究表明，在计算船体总纵强度时，必须考虑构件的屈曲、屈服等各种可能的破坏模式，要考虑受压构件屈曲后及崩溃后非线性性能影响。
The study indicates we must take into account several possible destructive modes such as buckle and yield et al and consider the non-linear effect of post-buckling and post - collapse of components.
本文将拉丁超立方抽样法与条件期望和对偶变数方差减缩技术组合用于分析船体总纵极限强度可靠性。
This paper proposes Latin hypercube sampling combined with variance reduction techniques of conditional expectation and antithetic variates to assess ultimate strength reliability of ship hull girder.
